Thanks, I will definitely post something on the Wiki when I have some time..
Thanks.
I'll try with tuned balanced vs powersave see what happens..
Feel free to share. Also don't forget to attend Fedora 19 power management test day :). It will be interesting to compare the results with others. This time we will try to focus more on video cards power savings. There is placeholder wiki [1] (will be reworked before the event).
The issue was that with Fedora the battery was terrible 7 hours in Windows 8 to 3 hours in Fedora (5 to 6 in Ubuntu).. I've just set up tuned so I don't know if that will make any difference, hope it does.
It seems we do not have optimal defaults in Fedora and the test day may also help to improve this. There are many aggressive (generally unsafe) tunings that may lower the power consumption (sometimes significantly). Feel free to send me output of # dmesg and html from # powertop --html for detailed analysis. I can propose some more aggressive tunings for you
